Oxford, United Kingdom
By day, I'm a software solution architect. What that means in practice is that I write system design documentation in language that non-technical users can understand.
By night I'm a jazz musician.
I have degrees in music and (separately) in Renaissance art history, neither of which are of any direct use in what I do (jazz especially is not something you learn from books); but both are of endless benefit in appreciating what others achieve in those fields.
